Applications of CR C Channel:

The CR C Channel can be applied to construction of warehouses, workshops, sport stadiums and car parks etc.The hot rolled channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery.In details, the hot rolled channel steel is usually used for arch-itechtural structure, and they could be welded in order to support or hang a vari-ety of facilities. They are also usually used in combination with I beam. Generally,the hot rolled channel steel we supply must possess perfect welding property, riveting property and mechanical property and so on.

 

 

Package & Delivery of CR C Channel:

1.The hot rolled channel steel will be packed in bundle with steel wire at each end of every bundle and color marking in order to help the customer to recognize his goods more easily at sight.

2. And the hot rolled channel steel could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches more than 3.5 mt, the loading by break bulk cargo should be choosed.When the weight of each bundle reaches less than 3mt, the loading by container should be choosed.

3.As for the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.

4.All in all, we could do in accordance with customer's request.

 

 CR C Channel

 

 Production Flow of CR C Channel:

1.The steel billet shall be heated in the high temperature furnace.

2. The heated steel billet shall be rolled five to nine times with the aim of shaping the general figure of steel u channel.

3. The hot rolled channel steel should be put onto the cooling bed to make the temperature low.

4. The channel steel should be straighted on the straightener.

5. The straighted channel steel will be cut into meters by saw, as per customer's requirements.

Q:How many tons per ton for channel 12?
12# channel steel appearance size: A. height 120 mm. Leg length 53 mm. Thickness 5 mmWhat is the length of 12# channel? Specifications: A. 6M12# how much is the current price of the channel steel ton?Answer: 3000-4000 yuan
Q:Duplex 3, the main beam 3.6 meters, span 4.5 meters wide, steel structure, with 8 channel steel can be, how much space? Or how to make it reasonable? Daily life bears little weight.
Channel steel deformation, it is recommended to cast in place concrete
Q:What's the weight of the 4 meter long 18 channel steel?
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:Is the crane telescopic arm welded by channel steel or by square tube?
You think, is certainly the square and thick wall, to ensure the overall stiffness and strength.When the channel steel is welded together, how can the weld be treated? If the welded joint is too high, it will affect the expansion of the inner and outer walls Flat and can not, and it can not be welded inside, how to ensure that the intensity?In order to save money by not crane factory this rough steel welding method, and crane safety first, but once the problem is not trivial, does not rule out a small factory dare to do so, but definitely not the formal business.This kind of profile is formed at one time without any subsequent welding. It is a pressing forming sleeve with cold drawing technology!
Q:Can the bypass of the overhanging layer on the site be made of channel steel? How can I put the channel steel, if possible?
JGJ130 2016.10.6 when the cantilever beam and the structure of the steel plate bolt connection fixed suspension type steel, steel plate size should not be less than 100mm * 10mm (width * thick); when the bolt angle plate connection, angle specifications shall not be less than 63mm * 63mm * 6mm.
Q:Roll an outer diameter of 1688MM groove steel ring, how to cut?
Count the amount, and in turn count how much it should be minus 1688, and then do it. Or leave a little margin, roll it repaired.
Q:What kind of steel products are there, such as channel steel, angle iron and so on?
Common types of wire Q195, Q215, Q235 three, but the construction of steel wire rod for only Q215, Q235 two, general specifications often with diameter 6.5mm, diameter 8.0mm, diameter 10mm, the country's largest diameter of wire rod can reach 30mm. Besides being used as reinforcing bars for building reinforced concrete, wire rod can also be used for wire drawing and wire mesh.
Q:Is channel steel expensive or angle expensive?
There is a difference in price for different specifications
Q:Own attic, choose I-beam or channel
GB gb. Don't look cheap.There are many impurities in non GB steel, and the yield and tensile strength are not qualified. Does not meet the use requirements.
Q:How do you calculate the weight of 100 channel steel?
CAD drawing can also be used to calculate the cross-sectional area of 100 channel, or other ways to first calculate the cross section area of 100 channel.
JANG is a professional company specilized in cold bend angle, cold bend U channel and other cold formed sectional steel. Since the established of our company, we aimed to provide the customers qualified product with good price and convenient service.
